Wearable antennas can suffer from a variety of mechanical deformations that are induced by the body dynamic. The paper analyses how these complex deformations impact the performance of a flexible antenna operating in the 5-6 GHz band. The Green Coordinates spatial manipulation technique is used to generate a range of complex two-dimensional deformations, namely spherical, saddle, and twisting deformation. Generating full geometries is a key enabler in this study. The results offer valuable insight to the stability of antenna performance under in-situ deformations.
